Making a golf ball that lights up in the dark does not seem too difficult. But making one that also feels and plays like a professional golf ball is a different story. John Gill, the inventor of the Twilight Tracer golf ball, explained it this way: ''Tiger Woods comes down at the ball at anywhere between 100 and 120 miles per hour. To have electronics that can take that type of force and keep on ticking over and over again, well, that's hard to do.''
